Tissue turnover refers to the continuous process of cells being replaced in a tissue. Old or damaged cells are removed and replaced with new cells through cell division and differentiation, ensuring the tissue remains healthy and functional. Examples of tissues with high turnover rates include the skin and the lining of the digestive tract.
When cells of a leaf or stem are damaged, they are replaced by nearby undifferentiated cells called meristematic cells. These cells have the ability to divide and differentiate into the specific cell types needed to repair the damage. In the case of a leaf, it is often the epidermal cells that are involved in this replacement process.
Skin cells are a type of epithelial cell that make up the outer layer of the skin. They provide a protective barrier for the body and are constantly being shed and replaced through a process of cell division.
Cells in the bone marrow, such as blood cells, divide more quickly than other body cells. Skin cells and intestinal cells also divide frequently to replace damaged or dying cells.
Skin cells are constantly being replaced, with old cells shedding and new ones being produced in the lower layers of the skin. This process can take anywhere from 2-4 weeks for complete turnover of the skin cells on the outermost layer known as the epidermis.

Currently, the parts of the body that can be replaced with cells include skin, blood, and bone marrow. Skin grafts can be used to replace damaged skin, blood transfusions can replace blood cells, and bone marrow transplants can be performed to replace damaged or diseased bone marrow. However, the ability to completely replace complex organs or tissues like the heart or liver with cells is still a developing field of research.
Cells in the bone marrow, such as blood cells, divide more quickly than other body cells. Skin cells and intestinal cells also divide frequently to replace damaged or dying cells.
Skin cells undergo mitosis to replace old or damaged cells, maintain the overall integrity of the skin, and facilitate wound healing. Additionally, mitosis helps in the growth and development of the skin during periods of growth.
Skin cells are damaged faster than your liver cells so the divide more often
Mitosis is the process by which cells divide to increase their numbers. When skin is damaged, mitosis allows skin cells to rapidly divide and replace the damaged cells, leading to the repair of the skin. This process helps in healing wounds and maintaining the integrity of the skin barrier.
Shed and replaced. This is a continuous process known as skin cell turnover, where dead skin cells are shed and new ones are generated to maintain healthy skin.
